Nope. The only problem with the plugs is on the 2004-2008 with the 5.4l.

 

4.6 is not a 3 valve, correct.

 

Gotcha...my 4.6 in my mustang is a 3v I thought they were 3vs in the truck too. I never looked much into the f150's but now that im getting one I started wasting time at work on here as well as my mustang sites lol

 

Let me get this straight. Ford Engineers design the engine, the cylinder head, the spark plug, then recognize there error, Post a TSB create tools to remove the plug and and all the while knowing this is there fault and ignorance in the design room, Decide to charge the consumer who is unaware until after the fact of purchasing this truck/car

Wow WAY to go ford, No wonder they don't need a bail out. Just Design reasons to rape and pillage its customers, if a ford mechanic breaks your plug, It should be there dime to remove it. and so it should be for the life of this engine.

I wonder how many trucks and cars they would sell if they said now, by purchasing this vehicle you do know that the plugs are prone to carbon build up which in turns, causes the tip of the two piece spark pug to stick and have the tip become detached and stuck inside the head. This will now cost you between 40 to 80 dollars a plug depending on the dealership. Oh did we not tell you the plugs are not cheap as well. We accept no responsibility for our screw up.

Sorry Ford I disagree with you.

 

^^^ Nice threadcrapping...

No breakage here.

 

No, you don't have it straight.

 

Well I am always up for learning something new, Tell me how ford knowing this defect and charging the consumers, I know the dealers are independently owned but Ford in itself could reimburse the consumer or dealer.

 

changed mine at 72'000 no tsb, no carb cleaner, just a deep 9/16 socket a cold engine and none broken.

 

Ford took care of this issue in mid 08 with a head redesign. That doesn't help previous owners, but the new trucks they are building now don't have this issue.

 

Sorry bluejay, i think mdniterder does have it straight. glc hit the nail on the head when he said "that doesn't help previous owners". I think ford ought to either eat the cost on these as long as it pleases us to drive them, or buy 'em back. if we're wrong, pls set us straight. unless you mean that Ford did not design the spark plug? hmmm... point, but not good enough. I think that counts as a "Ford knew, or should have known, the spark plugs break". if only a few in the history of that series did it, OK, stuff happens. but it sounds like it's happening way too much to be "stuff happens".

Ford's not alone in this kind of nonsense, btw. first time i ever heard of this kind of thing was when Nissan installed $1500.00 headlights on one of their models. Owners got to find out when replacing them after accidents. whee!

 

This is off subject for this thread and most of us are worn out from debating it. If you are interested in the discussion, it has been repeated in threads several times. Use the search button and advanced search. The last one was about 10 days ago, as I recall.

 

I could be wrong but I think in '09 & '10 (F-150) you can get either the 4.6 2V (standard) or the 4.6 3V as an option. With the 3V 4.6 in either of those years there still wouldn't be a problem with the plugs as all 3V's went to the redesigned heads and the redesigned 1 piece plugs in '08. From sometime in the '03 model year to current there should be no plug problems in the 2V 4.6 because they corrected the "not enough threads in the heads" problem in '03.

 

One of the reasons I went with the 4.6... and it is more then enough for my needs.

 

I forgot about the head redesign in 08....I remember reading about it on the mustang forums. Does anyone know if the 08 head are a direct swap onto a 05? Did I read also that the cam phaser (another issue in the 3v) was redone in the 08 heads?
